    Abstract: A scheduling apparatus and a scheduling method, wherein the amount of signaling for frequency resource allocation information can be reduced while maintaining system throughput performance. In a base station apparatus (100), a scheduling section (113) allocates frequency resources to frequency allocation target terminals based on set frequency allocation units, and a frequency allocation parameter setting section (112) adjusts the set frequency allocation units set in the scheduling section (113) based on cluster numbers. Due to this, in each cluster number, frequency resources can be allocated based on the most suitable frequency allocation units with respect to the signaling bit number. As a result, the amount of signaling for frequency resource allocation information can be reduced. Further, system throughput can be maintained by making the cluster number, which is a parameter having little effect on system throughput, a setting parameter for frequency allocation units.

    Abstract: A terminal device is equipped with: a sequence determination unit that determines a sequence number with a different pattern than the assignment pattern for the sequence number assigned to the cell in which the host device resides; a reference signal generation unit that generates a reference signal for a sequence group corresponding to the sequence number that has been determined; and a wireless transmission unit that transmits the reference signal that has been generated to a base station. The sequence determination unit employs a configuration whereby, with the sequence number assigned to the cell in which the host device resides as a cell-specific sequence number, a dynamic offset which periodically changes over time and for which the same value is not consecutive is added to the cell-specific sequence number, thereby determining a sequence number which never overlaps with the cell-specific sequence number.

    Abstract: The invention provides a base station that does not cause the number of blind decodings to be increased and further can prevent the flexibility of resource allocation from degrading. A search space setting unit (103) sets search spaces each of which is constituted by one or more control channel elements (CCEs) and each of which is to be decoded in the terminals and each of which is defined by a plurality of to-be-decoded candidates. An allocating unit (108) places, in one of the plurality of to-be-decoded candidates included in the search space, a control channel. The number of connections of CCEs constituting the to-be-decoded candidate is associated with the number of to-be-decoded candidates. The search space setting unit (103) causes, in accordance with the control channel to be transmitted, the association of the number of connections of CCEs constituting the to-be-decoded candidate with the number of to-be-decoded candidates to differ.

    Abstract: Provided is a terminal with which it is possible, in a heterogeneous cell network, to transmit a Periodic-Sounding Reference Signal (P-SRS) at a transmission bandwidth and power density necessary for carrying out both a process of selection of a transceiving participating base station and a process of frequency scheduling of a Packet Uplink Shared Channel (PUSCH).

    Abstract: Provided is a terminal apparatus in which, a transmission control unit (204) controls the transmission power of a sounding reference signal (SRS) by use of an offset value relative to the transmission power of a data signal, and a transmission unit (206) transmits the SRS by use of the transmission power as controlled. If a subframe to be used for transmitting the SRS is a predetermined subframe, the transmission control unit (204) uses a first offset value to control the transmission power of the SRS. Otherwise, the transmission control unit (204) uses a second offset value to control the transmission power of the SRS, The second offset value is an offset value that has been established so as to be transmitted to the serving cell of the terminal (200), and the first offset value is greater than the second offset value.

    Abstract: Se proporciona un dispositivo de comunicación y un método de transmisión SRS capaz de reducir la posibilidad de una diferencia en el reconocimiento entre la presencia o ausencia de una transmisión SRS entre una estación base y un terminal o de un recurso SRS de modo de evitar la degradación del rendimiento del sistema. En un terminal (200), una unidad de procesamiento de recepción (203) detecta información de control que indica si se debe solicitar o no la transmisión de una señal de referencia de sondeo (SRS), tras lo cual una unidad de formación de señal de transmisión (207) transmite una A-SRS mediante el control de una unidad de control de transmisión (206) sobre la base de la información de control. La unidad de control de transmisión (206) determina si se debe ejecutar o no la transmisión SRS sobre la base de una "Regla de ejecución de transmisión SRS" y el estado de recepción de la información de activación.

    Abstract: A terminal apparatus is disclosed wherein even in a case of applying SU-MIMO and MU-MIMO at the same time, the inter-sequence interference in a plurality of pilot signals used by the same terminal can be suppressed to a low value, while the inter-sequence interference in pilot signal between terminals can be reduced. In this terminal apparatus (200): a pilot information deciding unit (204) decides, based on allocation control information, Walsh sequences of the respective ones of first and second stream groups at least one of which includes a plurality of streams; and a pilot signal generating unit (205) forms a transport signal by using the decided Walsh sequences to spread the streams included in the first and second stream groups. During this, Walsh sequences orthogonal to each other are established in the first and second stream groups, and users are allocated on a stream group-by-stream group basis.
